About This Ranking

Schools are ranked by the College Scorecard's reported undergraduate student enrollment. Graduate enrollment is not included in this metric. Only schools with reported undergraduate enrollment are included. All data comes from the U.S. Department of Education College Scorecard. See our methodology for reporting-year details.

Caveats and limitations

Undergraduate enrollment measures the size of the undergraduate student body, not selectivity, quality, or student experience - some of the largest schools here operate heavily online, so their headcount does not translate directly into a comparable on-campus population.

Reported enrollment can include degree-seeking and non-degree-seeking undergraduates depending on how each institution submits data to IPEDS, so headcounts are not perfectly apples-to-apples across schools.

This ranking is for informational purposes only and does not constitute educational advice. Undergraduate enrollment measures scale, not fit, quality, or outcomes for any individual student.
